General von Flockenstuffen is introduced in the episode "Watch the Birdie" and retired in "An Almighty Bang". In his first episode, he is revealed to be a "bit this way and that" like Gruber. He is a former member of the Condor Legion, a German unit apparently known for its bold operations. In Free At Last!, he and a fellow General plan a recklessly daring to abduct Winston Churchill from Bognor in England while Klinkerhoffen is on medical leave, planning to have von Strohm, Gruber and Bertorelli take part in the operation as a suicide squad to create a diversion. Fortunately, the plan never comes into action as they help Klinkerhoffen escape from the institution and von Flockenstuffen goes mad after being blown up.

The other minor General characters introduced at the same time as von Flockenstuffen are General Wilhelm Von Walkenstiffen, Air Chief Marshal Maximilian Von Winkelmeister, Admiral Ulrich Von Sinkenquicken, and (French) General Jean-Louis Marcel Esnovor (at first impersonated by Crabtree).
